Since we don't catch all hwsim attribute types in unicast_handler
you see tons of "Unknown attribute type: X" prints. Since this is
not an error, we should only print if the attribute does not exist
in the attribute list.
In out-of-tree builds without dependency tracking the src/ directory generally
won't be created before genbuiltin tries to write into it. Fix the race by
explicitly creating the directory.

Single AVP should not be padded with zeros as padding is only
used to separate AVPs in a sequence.
RFC 5281 Section 10.2. AVP Sequences
Data encapsulated within the TLS record layer must consist entirely
of a sequence of zero or more AVPs. Each AVP must begin on a four-
octet boundary relative to the first AVP in the sequence. If an AVP
is not a multiple of four octets, it must be padded with zeros to the
next four-octet boundary.
Note that the AVP Length does not include the padding.
